The Lowdown
Alright folks, Rusty here. Let's be straight with you. We've got a grim stretch ahead for Kennebunk Beach. The data's pretty clear: we're looking at a long, dry spell.
Over the next two weeks, there's really nothing worth paddling out for. We've got a gap of about ten days with absolutely nothing to recommend. The swell is tiny and weak, the winds are mostly rubbish, and the surf quality just isn't there. The energy in the water is consistently weak, with combined swell energy values barely cracking the triple digits on a couple of occasions, but still well under 200. This is a classic case of a sheltered spot, exposed to the east-northeast but getting mostly low-energy, short-period windswell.
Saturday, 22 August kicks things off with a poor outlook. A small 2ft swell from the ESE with a clean, offshore northeast breeze, but it's just not enough to work with. The water's sitting at 66°, about average for the time of year. This theme continues through the next week. Wednesday morning, 2 September, is a glimmer of hope in a very ordinary outlook. We get a 2ft SE swell with a 12-second period, giving us a touch of groundswell energy (122), and the winds are light from the east-northeast, keeping it clean. But it's still small and not worth getting excited about. That's about as close as we get to a recommendation.
Honestly, for the whole 16-day run, the swell never gets above 4ft and that’s only on Monday, 24 August, but with a cross-onshore wind and a short, gutless period. Even with that little 3ft glassy morning on Saturday, 29 August, the energy is just too low. We're talking tiny, weak waves. If you’re a beginner looking for a bob around, maybe the clean morning of the 2nd of September is your window.
Otherwise, this is a blank run for the area. It's not uncommon for Kennebunk Beach to go quiet for a stretch. The forecasts can change, but for now, don't hold your breath.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
